Compared with the prior art, the beneficial effects of the utility model are as follows:
(1) the exhaust pipe support is formed by overlapping two layers of metal plates, so that the support strength of the exhaust pipe support is ensured.
(2) The hard material plate is made of a stainless steel plate which has stable chemical properties and is resistant to corrosion of weak corrosive media such as air, steam, water and the like.
(3) The sheet is provided with a large number of micropores to form sound-absorbing holes, so that on one hand, the sound-absorbing system can be improved due to the small aperture, and on the other hand, the width of a sound-absorbing frequency band can be increased due to the low porosity, so that the purpose of eliminating noise can be achieved.
(4) The strengthening rib not only can improve the structural strength of support body, forms into the second order bending mode that protruding or sunken strengthening rib can further improve the support body moreover to reduce the resonance of support body and the relative automobile body of blast pipe, thereby improve the life of support body.
